    abstract =  {The document describes a mechanism allowing the use of Duplicate Address Detection (DAD) by IPv6 nodes in a point-to-multipoint architecture with "split-horizon" forwarding scheme. Based on the DAD signalling, the first hop router stores in a Binding Table all known IPv6 addresses used on a point-to-multipoint domain (e.g. VLAN). When a node performs DAD for an address already used by another node, the first hop router replies instead of this last one.},
